Modern-day student Yoshiharu finds himself unexpectedly teleported back in time and smack dab in the middle of a battle. When a soldier sacrifices his life to save Yoshiharu, it’s up to him to fulfill his dying wish. But Yoshiharu hasn’t just gone back in time- he’s gone to an entirely different timeline altogether! Here, the warriors of old are instead beautiful young women, and the legendary warlord Nobunaga Oda is now the voluptuous Nobuna Oda- and she wants Yoshiharu to serve at her side.
The capital of Kyoto is unexpectedly attacked by the Miyoshi Three, thwarting Nobuna's attempt to take the capital for herself. Now Yoshiharu realizes that the history as he knows it is much different from the events now unfolding before him.
